Trolli Forza Promotion

I’ve looked at the Trolli website and it gives me retailers that sell the Trolli Brite Crawlers, but their inventory doesn’t show the Forza branding on the packaging

Does the product you buy and the receipt you upload even need to have the Forza on the packaging and it can be any Trolli brite crawlers / popsicles?

But on the other hand I’m thinking that doesn’t make sense because how will they know you want the Forza promotion over the Diablo promotion

Just need a little guidance here idk
